2. What is the difference between an unspecified passive open and a fully specified passive openAn unspecified passive open has the server waiting for a connection request from a client. A fully specified passive open has the server waiting for a connection from aspecific client.

3. Explain the function of Transmission Control BlockA TCB is a complex data structure that contains a considerable amount of information about each connection.

4. What is a Management Information Base (MIB)A Management Information Base is part of every SNMP-managed device. Each SNMP agent has the MIB database that contains information about the device's status, itsperformance, connections, and configuration. The MIB is queried by SNMP.

5. What is anonymous FTP and why would you use itAnonymous FTP enables users to connect to a host without using a valid login and password. Usually, anonymous FTP uses a login called anonymous or guest, with thepassword usually requesting the user's ID for tracking purposes only. Anonymous FTP is used to enable a large number of users to access files on the host without havingto go to the trouble of setting up logins for them all. Anonymous FTP systems usually have strict controls over the areas an anonymous user can access.

6. What is a pseudo tty A pseudo tty or false terminal enables external machines to connect through Telnet or rlogin. Without a pseudo tty, no connection can take place.

7. What is REXWhat advantage does REX offer other similar utilities

8. What does the Mount protocol doThe Mount protocol returns a file handle and the name of the file system in which a requested file resides. The message is sent to the client from the server after reception of a client's request.

9. What is External Data Representation External Data Representation is a method of encoding data within an RPC message, used to ensure that the data is not system-dependent.

10. What is the Network Time Protocol ?

11. BOOTP helps a diskless workstation boot. How does it get a message to the network lookingfor its IP address and the location of its operating system boot files BOOTP sends a UDP message with a subnetwork broadcast address and waits for a reply from a server that gives it the IP address. The same message might contain the name of the machine that has the boot files on it. If the boot image location is not specified, the workstation sends another UDP message to query the server.

12. What is a DNS resource recordA resource record is an entry in a name server's database. There are several types of resource records used, including name-to-address resolution information. Resourcerecords are maintained as ASCII files.

13. What protocol is used by DNS name serversDNS uses UDP for communication between servers. It is a better choice than TCP because of the improved speed a connectionless protocol offers. Of course,transmission reliability suffers with UDP.14. What is the difference between interior and exterior neighbor gatewaysInterior gateways connect LANs of one organization, whereas exterior gateways connect the organization to the outside world.

15. What is the HELLO protocol used forThe HELLO protocol uses time instead of distance to determine optimal routing. It is an alternative to the RoutingInformation Protocol.

16. What are the advantages and disadvantages of the three types of routing tablesThe three types of routing tables are fixed, dynamic, and fixed central. The fixed table must be manually modified every time there is a change. A dynamic table changes itsinformation based on network traffic, reducing the amount of manual maintenance. A fixed central table lets a manager modify only one table, which is then read by otherdevices. The fixed central table reduces the need to update each machine's table, as with the fixed table. Usually a dynamic table causes the fewest problems for a networkadministrator, although the table's contents can change without the administrator being aware of the change.

17. What is a TCP connection table18. What is source routeIt is a sequence of IP addresses identifying the route a datagram must follow. A source route may optionally be included in an IP datagram header.

19. What is RIP (Routing Information Protocol)It is a simple protocol used to exchange information between the routers.

20. What is SLIP (Serial Line Interface Protocol)It is a very simple protocol used for transmission of IP datagrams across a serial line.

What is OSPFIt is an Internet routing protocol that scales well, can route traffic along multiple paths, and uses knowledge of an Internet's topology to make accurate routing decisions.

23. What is KerberosIt is an authentication service developed at the Massachusetts Institute of Technology. Kerberos uses encryption to prevent intruders from discovering passwords and gaining unauthorized access to files.24. What is a Multi-homed HostIt is a host that has a multiple network interfaces and that requires m ultiple IP addresses is called as a Multi-homed Host.

25. What is NVT (Network Virtual Terminal)It is a set of rules defining a very simple virtual terminal interaction. The NVT is used in the start of a Telnet session.26. What is Gateway-to-Gateway protocolIt is a protocol formerly used to exchange routing information between Internet core routers.

27. What is BGP (Border Gateway Protocol)It is a protocol used to advertise the set of networks that can be reached with in an autonomous system. BGP enables this information to be shared with the autonomoussystem. This is newer than EGP (Exterior Gateway Protocol).

28. What is autonomous systemIt is a collection of routers under the control of a single administrative authority and that uses a common Interior Gateway Protocol.

29. What is EGP (Exterior Gateway Protocol)It is the protocol the routers in neighboring autonomous systems use to identify the set of networks that can be reachedwithin or via each autonomous system.Computer Networks Interview Questions30.

The most common three letter combinations are called as trigrams. e.g. the, ing,and, and ion.34. What is silly window syndromeIt is a problem that can ruin TCP performance. This problem occurs when data are passed to the sending TCP entity in large blocks, but an interactive application on thereceiving side reads 1 byte at a time.35. What is regionWhen hierarchical routing is used, the routers are divided into what we call regions, with each router knowing all the details about how to route packets to destinationswithin its own region, but knowing nothing about the internal structure of other regions.36. What is multicast routingSending a message to a group is called multicasting, and its routing algorithm is called multicast routing.37. What is traffic shapingOne of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate,congestion would be less common. Another open loopmethod to help manage congestion is forcing the packet to be transmitted at a more predictable rate. This is calledtraffic shaping.38. What is packet filterPacket filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming oroutgoing packet to be inspected. Packets meetingsome criterion are forwarded normally. Those that fail the test are dropped.39. What is virtual pathAlong any transmission path from a given source to a given destination, a group of virtual circuits can be groupedtogether into what is called path.Computer Networks Interview Questions40. What is virtual channelVirtual channel is normally a connection from one source to one destination, although multicast connections are alsopermitted. The other name for virtual channel is virtualcircuit.41. What is logical link controlOne of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sublayeris responsible for maintaining the link betweencomputers when they are sending data across the physical network connection.42. Why should you care about the OSI Reference ModelIt provides a framework for discussing network operations and design.43. What is the difference between routable and non- routable protocolsRoutable protocols can work with a router and can be used to build large networks. Non-Routable protocols aredesigned to work on small, local networks and cannot beused with a router44. What is MAUIn token Ring , hub is called Multistation Access Unit(MAU).45. Explain 5-4-3 ruleIn a Ethernet network, between any two points on the network, there can be no more than five network segments or fourrepeaters, and of those five segments only three ofsegments can be populated.46. What is the difference between TFTP and FTP application layer protocolsThe Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not providereliability or security. It uses the fundamental packetdelivery services offered by UDP.The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host toanother. It uses the services offered by TCP and so isreliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and anotherfor control information.47. What is the range of addresses in the classes of internet addressesClass A 0.0.0.0 - 127.255.255.255Class B 128.0.0.0 - 191.255.255.255Class C 192.0.0.0 - 223.255.255.255Class D 224.0.0.0 - 239.255.255.255Class E 240.0.0.0 - 247.255.255.25548.

How Gateway is different from RoutersA gateway operates at the upper levels of the OSI model and translates information between two completely differentnetwork architectures or data formats.69. What are the different type of networking / internetworking devicesRepeater:Also called a regenerator, it is an electronic device that operates only at physical layer. It receives the signal in thenetwork before it becomes weak, regenerates the originalbit pattern and puts the refreshed copy back in to the link.Bridges:These operate both in the physical and data link layers of LANs of same type. They divide a larger network in to smallersegments. They contain logic that allow them tokeep the traffic for each segment separate and thus are repeaters that relay a frame only the side of the segmentcontaining the intended recipent and control congestion.Routers:They relay packets among multiple interconnected networks (i.e. LANs of different type). They operate in the physical,data link and network layers. They contain softwarethat enable them to determine which of the several possible paths is the best for a particular transmission.Gateways:They relay packets among networks that have different protocols (e.g. between a LAN and a WAN). They accept apacket formatted for one protocol and convert it to apacket formatted for another protocol before forwarding it. They operate in all seven layers of the OSI model.70. What is mesh networkA network in which there are multiple network links between computers to provide multiple paths for data to travel.71. What is passive topologyWhen the computers on the network simply listen and receive the signal, they are referred to as passive because theydon’t amplify the signal in any way.

What are major types of networks and explainServer-based networkPeer-to-peer networkPeer-to-peer network, computers can act as both servers sharing resources and as clients using the resources.Server-based networks provide centralized control of network resources and rely on server computers to providesecurity and network administration74. What is Protocol Data UnitThe data unit in the LLC level is called the protocol data unit (PDU). The PDU contains of four fields a destinationservice access point (DSAP), a source service accesspoint (SSAP), a control field and an information field. DSAP, SSAP are addresses used by the LLC to identify theprotocol stacks on the receiving and sending machinesthat are generating and using the data. The control field specifies whether the PDU frame is a information frame (I -frame) or a supervisory frame (S - frame) or aunnumbered frame (U - frame).75. What is difference between baseband and broadband transmissionIn a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadbandtransmission, signals are sent on multiple frequencies, allowingmultiple signals to be sent simultaneously.76. What are the possible ways of data exchange(i) Simplex (ii) Half-duplex (iii) Full-duplex.77. What are the types of Transmission mediaSignals are usually transmitted over some transmission media that are broadly classified in to two categories.Guided Media:These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-opticcable. A signal traveling along any of these mediais directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that acceptand transport signals in the form of electricalcurrent. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.Unguided Media:This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals arebroadcast either through air. This is done through radiocommunication, satellite communication and cellular telephony.78. What is point-to-point protocolComputer Networks Interview QuestionsA communications protocol used to connect computers to remote networking services including Internet serviceproviders.79. What are the two types of transmission technology available(i) Broadcast and (ii) point-to-point80. Difference between the communication and transmission.Transmission is a physical movement of information and concern issues like bit polarity, synchronization, clock etc.Communication means the meaning full exchange of information between two communication media.

1. Construct pipes to execute the following jobs.1. Output of who should be displayed on the screen with value of total number of users who have logged in displayed at the bottom of the list.

2. Output of ls should be displayed on the screen and from this output the lines containing the word ‘poem’ should be counted and the count should be stored in a file.

3. Contents of file1 and file2 should be displayed on the screen and this output should be appended in a file. From output of ls the lines containing ‘poem’ should be displayed on the screen along with the count.

4. Name of cities should be accepted from the keyboard . This list should be combined with the list present in a file. This combined list should be sorted and the sorted listshould be stored in a file ‘newcity’.

5. All files present in a directory dir1 should be deleted any error while deleting should be stored in a file ‘errorlog’.

3. What is the significance of the “tee” command?It reads the standard input and sends it to the standard output while redirecting a copy of what it has read to the file specified by the user.

4. What does the command “ $who | sort –logfile > newfile” do?The input from a pipe can be combined with the input from a file . The trick is to use the special symbol “-“ (a hyphen) for those commands that recognize the hyphen as std input.In the above command the output from who becomes the std input to sort , meanwhile sort opens the file logfile, the contents of this file is sorted together with the output of who (rep by the hyphen) and the sorted output is redirected to the file newfile.

5. What does the command “$ls | wc –l > file1” do?ls becomes the input to wc which counts the number of lines it receives as input and instead of displaying this count , the value is stored in file1.

6. Which of the following commands is not a filter man , (b) cat , (c) pg , (d) headAns: manA filter is a program which can receive a flow of data from std input, process (or filter) it and send the result to the std output.

7. How is the command “$cat file2 “ different from “$cat >file2 and >> redirection operators ?is the output redirection operator when used it overwrites while >> operator appends into the file.

9. Explain the steps that a shell follows while processing a command.After the command line is terminated by the key, the shel goes ahead with processing the command line in one or more passes. The sequence is well defined and assumes the following order.Parsing: The shell first breaks up the command line into words, using spaces and the delimiters, unless quoted. All consecutive occurrences of a space or tab are replaced here with a single space.Variable evaluation: All words preceded by a $ are avaluated as variables, unless quoted or escaped.Command substitution: Any command surrounded by backquotes is executed by the shell which t hen replaces the standard output of the command into the command line.Wild-card interpretation: The shell finally scans the command line for wild-cards (the characters *, ?, [, ]).Any word containing a wild-card is replaced by a sorted list of filenames that match the pattern. The list of these filenames then forms the arguments to the command.PATH evaluation: It finally looks for the PATH variable to determine the sequence of directories it has to search in order to hunt for the command.

10. What difference between cmp and diff commands?cmp - Compares two files byte by byte and displays the first mismatchdiff - tells the changes to be made to make the files identical

11. What is the use of ‘grep’ command?‘grep’ is a pattern search command. It searches for the pattern, specified in the command line with appropriate option, in a file(s).Syntax : grepExample : grep 99mx mcafile

12. What is the difference between cat and more command?Cat displays file contents. If the file is large the contents scroll off the screen before we view it. Socommand 'more' is like a pager which displays the contents page by page.

13. Write a command to kill the last background job?Kill $!

14. Which command is used to delete all files in the current directory and all its sub-directories?rm -r *

16. What will the following command do?$ echo *It is similar to 'ls' command and displays all the files in the current directory.

17. Is it possible to create new a file system in UNIX?Yes, ‘mkfs’ is used to create a new file system.18. Is it possible to restrict incoming message?Yes, using the ‘mesg’ command.

19. What is the use of the command "ls -x chapter[1-5]"ls stands for list; so it displays the list of the files that starts with 'chapter' with suffix '1' to '5', chapter1,chapter2, and so on.

20. Is ‘du’ a command? If so, what is its use?Yes, it stands for ‘disk usage’. With the help of this command you can find the disk capacity and free space of the disk.

21. Is it possible to count number char, line in a file; if so, How?Yes, wc-stands for word count.wc -c for counting number of characters in a file.wc -l for counting lines in a file.

22. Name the data structure used to maintain file identification?‘inode’, each file has a separate inode and a unique inode number.

23. How many prompts are available in a UNIX system?Two prompts, PS1 (Primary Prompt), PS2 (Secondary Prompt).

24. How does the kernel differentiate device files and ordinary files?

Kernel checks 'type' field in the file's inode structure.

25. How to switch to a super user status to gain privileges?Use ‘su’ command. The system asks for password and when valid entry is made the user gains super user (admin) privileges.

26. What are shell variables?Shell variables are special variables, a name-value pair created and maintained by the shell.Example: PATH, HOME, MAIL and TERM

27. What is redirection?Directing the flow of data to the file or from the file for input or output.Example : ls > wc

28. How to terminate a process which is running and the specialty on command kill 0?With the help of kill command we can terminate the process.Syntax: kill pidKill 0 - kills all processes in your system except the login shell.

29. What is a pipe and give an example?A pipe is two or more commands separated by pipe char '|'. That tells the shell to arrange for the output of the preceding command to be passed as input to the following command.Example : ls -l | prThe output for a command ls is the standard input of pr. When a sequence of commands are combined using pipe, then it is called pipeline.

30. Explain kill() and its possible return values.There are four possible results from this call:‘kill()’ returns 0. This implies that a process exists with the given PID, and the system would allow you to send signals to it. It is system-dependent whether the process could be a zombie.‘kill()’ returns -1, ‘errno == ESRCH’ either no process exists with the given PID, or security enhancements are causing the system to deny its existence. (On some systems, the process could be a zombie.) ‘kill()’ returns -1, ‘errno == EPERM’ the system would not allow you to kill the specified process. This means that either the process exists (again, it could be a zombie) or draconian security enhancements are present (e.g. your process is not allowed to send signals to *anybody*). ‘kill()’ returns -1, with some other value of ‘errno’ you are in trouble! The most-used technique is to assume that success or failure with ‘EPERM’ implies that the process exists, and any other error implies that it doesn't.An alternative exists, if you are writing specifically for a system (or all those systems) that provide a ‘/proc’ filesystem: checking for the existence of ‘/proc/PID’ may work.

MS SQL Server interview questionsThis one always gets asked. For a while the database interview questions were limited to Oracle and generic database design questions. This is a set of more than a hundred Microsoft SQL Server interview questions. Some questions are open-ended, and some do not have answers.

What is normalization? - Well a relational database is basically composed of tables that contain related data. So the Process of organizing this data into tables is actually referred to as normalization.What is a Stored Procedure? - Its nothing but a set of T-SQL statements combined to perform a single task of several tasks. Its basically like a Macro so when you invoke the Stored procedure, you actually run a set of statements.Can you give an example of Stored Procedure? - sp_helpdb , sp_who2, sp_renamedb are a set of system defined stored procedures. We can also have user defined stored procedures which can be called in similar way.What is a trigger? - Triggers are basically used to implement business rules. Triggers is also similar to stored procedures. The difference is that it can be activated when data is added or edited or deleted from a table in a database.What is a view? - If we have several tables in a db and we want to view only specific columns from specific tables we can go for views. It would also suffice the needs of security some times allowing specfic users to see only specific columns based on the permission that we can configure on the view. Views also reduce the effort that is required for writing queries to access specific columns every time.What is an Index? - When queries are run against a db, an index on that db basically helps in the way the data is sorted to process the query for faster and data retrievals are much faster when we have an index.What are the types of indexes available with SQL Server? - There are basically two types of indexes that we use with the SQL Server. Clustered and the Non-Clustered.What is the basic difference between clustered and a non-clustered index? - The difference is that, Clustered index is unique for any given table and we can have only one clustered index on a table. The leaf level of a clustered index is the actual data and the data is resorted in case of clustered index. Whereas in case of non-clustered index the leaf level is actually a pointer to the data in rows so we can have as many non-clustered indexes as we can on the db.What are cursors? - Well cursors help us to do an operation on a set of data that we retreive by commands such as Select columns from table. For example : If we have duplicate records in a table we can remove it by declaring a cursor which would check the records during retreival one by one and remove rows which have duplicate values.When do we use the UPDATE_STATISTICS command? - This command is basically used when we do a large processing of data. If we do a large amount of deletions any modification or Bulk Copy into the tables, we need to basically update the indexes to take these changes into account. UPDATE_STATISTICS updates the indexes on these tables accordingly.Which TCP/IP port does SQL Server run on? - SQL Server runs on port 1433 but we can also change it for better security.From where can you change the default port? - From the Network Utility TCP/IP properties –> Port number.both on client and the server.Can you tell me the difference between DELETE & TRUNCATE commands? - Delete command removes the rows from a table based on the condition that we provide with a WHERE clause. Truncate will actually remove all the rows from a table and there will be no data in the table after we run the truncate command.Can we use Truncate command on a table which is referenced by FOREIGN KEY? - No. We cannot use Truncate command on a table with Foreign Key because of referential integrity.What is the use of DBCC commands? - DBCC stands for database consistency checker. We use these commands to check the consistency of the databases, i.e., maintenance, validation task and status checks.Can you give me some DBCC command options?(Database consistency check) - DBCC CHECKDB - Ensures that tables in the db and the indexes are correctly linked.and DBCC CHECKALLOC - To check that all pages in a db are correctly allocated. DBCC SQLPERF - It gives report on current usage of transaction log in percentage. DBCC CHECKFILEGROUP - Checks all tables file group for any damage.What command do we use to rename a db? - sp_renamedb ‘oldname’ , ‘newname’Well sometimes sp_reanmedb may not work you know because if some one is using the db it will not accept this command so what do you think you can do in such cases? - In such cases we can first bring to db to single user using sp_dboptions and then we can rename that db and then we can rerun the sp_dboptions command to remove the single user mode.What is the difference between a HAVING CLAUSE and a WHERE CLAUSE? - Having Clause is basically used only with the GROUP BY function in a query. WHERE Clause is applied to each row before they are part of the GROUP BY function in a query.What do you mean by COLLATION? - Collation is basically the sort order. There are three types of sort order Dictionary case sensitive, Dictonary - case insensitive and Binary.What is a Join in SQL Server? - Join actually puts data from two or more tables into a single result set.Can you explain the types of Joins that we can have with Sql Server? - There are three types of joins: Inner Join, Outer Join, Cross JoinWhen do you use SQL Profiler? - SQL Profiler utility allows us to basically track connections to the SQL Server and also determine activities such as which SQL Scripts are running, failed jobs etc..What is a Linked Server? - Linked Servers is a concept in SQL Server by which we can add other SQL Server to a Group and query both the SQL Server dbs using T-SQL Statements.Can you link only other SQL Servers or any database servers such as Oracle? - We can link any server provided we have the OLE-DB provider from Microsoft to allow a link. For Oracle we have a OLE-DB provider for oracle that microsoft provides to add it as a linked server to the sql server group.Which stored procedure will you be running to add a linked server? - sp_addlinkedserver, sp_addlinkedsrvloginWhat are the OS services that the SQL Server installation adds? - MS SQL SERVER SERVICE, SQL AGENT SERVICE, DTC (Distribution transac co-ordinator)Can you explain the role of each service? - SQL SERVER - is for running the databases SQL AGENT - is for automation such as Jobs, DB Maintanance, Backups DTC - Is for linking and connecting to other SQL ServersHow do you troubleshoot SQL Server if its running very slow? - First check the processor and memory usage to see that processor is not above 80% utilization and memory not above 40-45% utilization then check the disk utilization using Performance Monitor, Secondly, use SQL Profiler to check for the users and current SQL activities and jobs running which might be a problem. Third would be to run UPDATE_STATISTICS command to update the indexesLets say due to N/W or Security issues client is not able to connect to server or vice versa. How do you troubleshoot? - First I will look to ensure that port settings are proper on server and client Network utility for connections. ODBC is properly configured at client end for connection ——Makepipe & readpipe are utilities to check for connection. Makepipe is run on Server and readpipe on client to check for any connection issues.What are the authentication modes in SQL Server? - Windows mode and mixed mode (SQL & Windows).Where do you think the users names and passwords will be stored in sql server? - They get stored in master db in the sysxlogins table.What is log shipping? Can we do logshipping with SQL Server 7.0 - Logshipping is a new feature of SQL Server 2000. We should have two SQL Server - Enterprise Editions. From Enterprise Manager we can configure the logshipping. In logshipping the transactional log file from one server is automatically updated into the backup database on the other server. If one server fails, the other server will have the same db and we can use this as the DR (disaster recovery) plan.Let us say the SQL Server crashed and you are rebuilding the databases including the master database what procedure to you follow? - For restoring the master db we have to stop the SQL Server first and then from command line we can type SQLSERVER .m which will basically bring it into the maintenance mode after which we can restore the master db.Let us say master db itself has no backup. Now you have to rebuild the db so what kind of action do you take? - (I am not sure- but I think we have a command to do it).What is BCP? When do we use it? - BulkCopy is a tool used to copy huge amount of data from tables and views. But it won’t copy the structures of the same.What should we do to copy the tables, schema and views from one SQL Server to another? - We have to write some DTS packages for it.What are the different types of joins and what dies each do?What are the four main query statements?What is a sub-query? When would you use one?What is a NOLOCK?What are three SQL keywords used to change or set someone’s permissions?What is the difference between HAVING clause and the WHERE clause?What is referential integrity? What are the advantages of it?What is database normalization?Which command using Query Analyzer will give you the version of SQL server and operating system?Using query analyzer, name 3 ways you can get an accurate count of the number of records in a table?What is the purpose of using COLLATE in a query?What is a trigger?What is one of the first things you would do to increase performance of a query? For example, a boss tells you that “a query that ran yesterday took 30 seconds, but today it takes 6 minutes”What is an execution plan? When would you use it?

JDBC and JSP interview questionsWhat is the query used to display all tables names in SQL Server (Query analyzer)?

select * from information_schema.tables

How many types of JDBC Drivers are present and what are they?- There are 4 types of JDBC DriversJDBC-ODBC Bridge Driver

Native API Partly Java DriverNetwork protocol DriverJDBC Net pure Java DriverCan we implement an interface in a JSP?- NoWhat is the difference between ServletContext and PageContext?- ServletContext: Gives the information about the container. PageContext: Gives the information about the RequestWhat is the difference in using request.getRequestDispatcher() and context.getRequestDispatcher()?- request.getRequestDispatcher(path): In order to create it we need to give the relative path of the resource, context.getRequestDispatcher(path): In order to create it we need to give the absolute path of the resource.How to pass information from JSP to included JSP?- Using tag.What is the difference between directive include and jsp include?- : Used to include static resources during translation time. JSP include: Used to include dynamic content or static content during runtime.What is the difference between RequestDispatcher and sendRedirect?- RequestDispatcher: server-side redirect with request and response objects. sendRedirect : Client-side redirect with new request and response objects.How does JSP handle runtime exceptions?- Using errorPage attribute of page directive and also we need to specify isErrorPage=true if the current page is intended to URL redirecting of a JSP.How do you delete a Cookie within a JSP? Cookie mycook = new Cookie(\"name\",\"value\"); response.addCookie(mycook); Cookie killmycook = new Cookie(\"mycook\",\"value\"); killmycook.setMaxAge(0); killmycook.setPath(\"/\"); killmycook.addCookie(killmycook);

How do I mix JSP and SSI #include?- If you’re just including raw HTML, use the #include directive as usual inside your .jsp file.

But it’s a little trickier if you want the server to evaluate any JSP code that’s inside the included file. If your data.inc file contains jsp code you will have to use

The is used for including non-JSP files.

I made my class Cloneable but I still get Can’t access protected method clone. Why?- Some of the Java books imply that all you have to do in order to have your class support clone() is implement the Cloneable interface. Not so. Perhaps that was the intent at some point, but that’s not the way it works currently. As it stands, you have to implement your own public clone() method, even if it doesn’t do anything special and just calls super.clone().Why is XML such an important development?- It removes two constraints which were holding back Web developments: dependence on a single, inflexible document type (HTML) which was being much abused for tasks it was never designed for; the complexity of full SGML, whose syntax allows many powerful but hard-to-program options. XML allows the flexible development of user-defined document types. It provides a robust, non-proprietary, persistent, and verifiable file format for the storage and transmission of text and data both on and off the Web; and it removes the more complex options of SGML, making it easier to program for.What is the fastest type of JDBC driver?- JDBC driver performance will depend on a number of issues:the quality of the driver code,

the size of the driver code,the database server and its load,network topology,the number of times your request is translated to a different API.In general, all things being equal, you can assume that the more your request and response change hands, the slower it will be. This means that Type 1 and Type 3 drivers will be slower than Type 2 drivers (the database calls are make at least three translations versus two), and Type 4 drivers are the fastest (only one translation).

How do I find whether a parameter exists in the request object?boolean hasFoo = !(request.getParameter(\"foo\") == null || request.getParameter(\"foo\").equals(\"\"));

How can I send user authentication information while makingURLConnection?- You’ll want to use HttpURLConnection.setRequestProperty and set all the appropriate headers to HTTP authorization.
